2 Claims.

For a detailed description of the present form of my invention,reference may be had to the following specication and to theaccompanying drawings forming a part thereof.

My invention consists in a bottle washer organized to performautomatically all of the operations required in cleansing bottles.

These operations include a preliminary rinsing,

a soaking in a tank containing a caustic solution, an emergence from thetank with an amount of said solution therein, a scrubbingboth internaland external, a draining out of any solution remaining therein, and afinal rinsing with fresh clean water. Means are provided for keeping thebottles moving through the several operations outlined above, beginningat the start, when vthey are first applied to the entrance conveyor andcontinued up to their nal delivery on the reception platform. Thisreception platform is located at the same end of the machine at whichthe bot- Together with the conveyance just mentioned there are, inaddition, auxiliary means for transferring the bottles from one conveyorto another at succeeding stages, including the ternporary ejection fromthe conveyor for washing, and their iinal ejection and setting up whenthe operations are finished.

Iwill rst describe the operations and will then describe the mechanismthat performs them.

Fig. 12a shows the carriers or buckets of the main conveyor.I

The machine in general comprises a rectangu- .lar casing of sheet metalpreferably left open at the center. This casing, with attachments, isabout twelve feet long and six feet high and its width, or horizontaldepth, is dependent on the number of lines of bottles passing through itin parallel lines. With four such lines the width, or depth, is aboutfour feet. The capacity of the machine may be changed by adding to, orsubtracting from, the number of such lines of travelling bottles.

In this casing there is one fundamental conveyor, travellingintermittently in a rectangular circuit, and consisting of two or moreparallel chains moving over guides and bridged across at intervals by aseries of upstanding sheet metal cells. buckets or carriers. This mainconveyor is illustrated in detail in Fig. 12B, wherein the several chainlinks are marked A1'I and the rollers B1". Each link is formed with abracket a1'I to which is riveted one end of a set of sheet metalcarriers D11. There are in this illustration four such carriers in aset, and the remote end of the set is similarly attached, as shown inFig. 12, to a corresponding bracket all in a parallel chain on theopposite side of the machine. The cells, .buckets or carriers standabove the chains in Fig. 12, but on'the bottom rim of the machine theywill project below the chains, and will project to'right or left of thechains on the vertical rims. Just above Fig. 12a is Fig. 12, which showsa cross section of the top length of the rectangular casing,.and in thisFig. 12 these carriers D appear in section with a bottle in each. Thesecarriers D1'1 are open at each end for admitting or removing the bottlesand are somewhat larger in cross section than the bottles inside ofthem. That is to receive different szes of bottles and to avoid a tightllt.

In addition to the main conveyor aforesaid,

there are various short auxiliary conveyors; sim- Eli) ilar inprinciple, that lead to or from the main 011e.

Referring to Fig. 1 (Sheet 1) the start of the operation is there shown.At the right of the figure is an auxiliary conveyor, which we 'maydesignate as the entry-conveyor", for the bottles to be washed are rstapplied to it. Its details are shown in the small Fig, 1a on the samesheet. A top view of the entry conveyor and the bottle holders for thelbottles applied to this conveyor appears in Fig. 4, Sheet 4. Itcomprises two parallel chains E2, of which only one is shown in Fig. la,the links thereof being connected across at intervals by bridge platesE5 on which are the bottle holders E5 and E5. The head of the bottle isdropped in the socket-shaped part E5 of the holder, while the body ofthe bottle lies against the bracket-like part E5. Thus the bottle standsbottom-up in the holder at a slight angle (see Fig. 2, Sheet 2) when inplace on the entry conveyor. The upper run or length of thisentryconveyor moves to the left in Fig. l advancing the bottles towardthe machine. This entry-conveyor is located on the right and in linewith the main conveyor, see Fig. Li. The receiving table X20, at whichthe washed bottles finally arrive, is located at the same end of themachine, back of the said entry-conveyor and to the right thereof,looking toward the machine in Figs, l and As the upstanding bottles moveto the left, being guided by the rods F5 extending along their sides, asshown in Figs. l, 2 and ll, they enter between the prongs of a forkedguide F1 (see Figs. l and 1l) and are thereby steadied as they, one byone, reach the position of the last holder on the top run of theconveyor chain it this position they receive the preliminary rinsingjets from the nozzle F1 below them and .from the nozzle F2 above thebottle, in the spraying hood The water from nozzle F2 washes the outsideand that from nozzle F1 the inside, of the bottle. The water from therinsing collects in the sink F5 at the bottom of the enclosure and goesout by waste pipe F15, as appears in Fig. 2, Sheet 2. After being rinsedby these jets, the bottle, as it starts to turn over, strikes theweighted and pivoted guide g1. It4 is the side of the bottle near itsbottom end that collides with this guide g1 and the bottle is therebytwisted out of the holders E5, E6 and drops, neck foremost, intoaninclined chute G1.

The chute G1 leads the bottle to the main line of carriers D17 which areshown, on the left-hand side of Fig. l, as moving downward on theirvertical rims. In Fig. 2b, Sheet 2, a bottle from chute G1 is seenentering a cell or bucket D17 of the conveyor, while from the nexthigher cell or bucket D17 a bottle which has finished its washingexperience, is emerging. The said chute G1, besides being pivoted at itsright hand end by the pivot y2, as shown in Fig. 1, is also pivotallysupported at its left hand end by `a long vertical link gi which isattached at its upper end to a spring g as a support for one end of atrough W1o hereinafter to be described. By this means, should there beany failure in the alignment of the mouth of chute Gluwith the mouth ofthe bucket on D17, into which the chute delivers the bottle, the chuteG1 Will yield vertically to meet the mouth of the bucket. In the'eventof such misalignment being too great, the movement of the chute will besuipulling down on the link g3. The inside surface driven.

Intermediate its ends the link g3 is also used of chute G1 is ribbed onthe bottom, as shown at g5 in Fig. l, to provide for the smooth slidingof the bottles therein. As leach bottle enters a bucket it is positivelypushed from behind by a pad J1 on the end of a lever arm projecting froma shaft J5 which is rocked by means of a link J 6 as shown in Fig. l.

The bottle has now reached the main conveyor and has entered a buckettherein. The conveyor transports it downward into the lower horizontalpart of the casing which forms the soaking tank, as may be seen in crosssection in Fig. 11. In this tank is the coil of pipes H12 which carrieshot water for heating the tank. In this Fig. 11 the tops of the bottles,projecting above the buckets D17 are shown at K12 and their bottomsappear at K13. The buckets, being open at both ends, become iilled withthe solution from the tank, which solution is of a caustic nature, andtravel slowly along horizontally to the opposite end of the tank wherethe conveyor-chain turns upwardly bring ing the bottles to the scrubbingapparatus, as may be seen in Fig. 7, Sheet 7. For the scrubbingoperation the main conveyor is stopped for the time required by thatoperation. It may be said here that the main conveyor is also stoppedfor the nal removal of the bottles therefrom at the end oi theoperation. The intermittent movement of the main conveyor will beexplained later.

In Fig. 7, the bottles, moving 'upward in the buckets, as shown at theleft, are pushed. out of the buckets, by pushers O7, on the end ofpusher rods O5, against the brushes. The body brush R7 is best shown inthe sectional appearing in Fig. l1, Sheet ll. The sections of the brushare carried by a link-chain which passes over the sprocket wheels R12,R12 by one oi' which it is This brush bears against the under side ofthe row of four bottles, and the bottles are pressed down against thebrush by a flexible belt R5 which runs parallel to the brushes over thetwo pulleys R5 and, on its lower branch, over three smaller pressingrolls R11, R5, R5. The two end rolls Ra are mounted respectively on twoangle levers R9, R9, while the central roller R5 is carried by a smallerangle lever R1n and pressed downward by a spring T which is connected bya rod and spring arrangement T1 to one of the levers R2. When theangle-lever R1 presses the small pressing roll R11 against the belt-R5,the rod T1 is pulled to the right in the view shown in Fig. 11, thuscompressing spring T which bears against a portion of the angle-leverR10 whereby to thrust the central pressing roll R8 downwardly. Each ofthe said angle levers R9 carries a roller V12 on its outer leg which ispositioned' adjacent rods O4. 'I'he rod O1 is provided with a short camV13 and, in the longitudinal movement of the rods O4, the cams V13thrust the rollers V12 outwardly and upwardly .to accomplish thetightening of the flexible belt R5. A plan of the flexible belt R5, itspulleys R5 and the rollers R8 appears in Fig. 6, Sheet 6. It is by meansof this exible belt R5 that the bottlesare kept in rotation while thebrushes bear upon them.-

The flexible belt R5 is driven by means of a chain R50 extending betweenand around sprockets R51 and R52 Whichare respectively mounted on shaft3 and Qnthe shaft R53 supporting the pulley which carries belt R5 asshown atV the left in Fig. 11.

Referring again to Fig. 7, wherein the body brus'n R7 is showninlongitudinal section bearing against a bottle, there is similarlyshown the neck brushes U5, and U5 which bear against the outside thepusher. thebottles are carried upwardly by necks of the bottle. There isa pair of these neck brushes for each bottle, the upper one beingcarrled by a spring arm u1 and the lower one by a similar spring arm u2.carried respectively by rockshafts S10 and S12, as appears in Fig. 9. Asshown clearly in Figs. 6, l and 9, the collars and extensions thereforeS5 are keyed to the rock shaft S10 and provide mounting surfaces forarms u1. The rock shaft S10 'is provided with an upstanding arm 46 towhich spring U5 is attached. The spring thus normally retracts thebrushes U5 and the upper endv of the spring U3 is attached to the frameadjacent the part E10, as shown in Fig. '7`. Y n v From shaft S10project downward the arms B0 and from shaft S12 project upward thevcorresponding arms B1.

50, 6 and 7 (hereinafter described) moves back-A As the mouth-piece S11,Figs.

Ward away from the bottle, it hits the said arms B0 and B7 and rocks theshafts S10 and S12. forces the said spring-arm u1. which carriesneckbrush U5 down and spring-arm u2, which carries the other neck-brushU5 up, into contact with the neck of the bottles. This contact continuesuntil the mouth piece S1*1 again moves back,.to push the bottles backinto the carrierV cell or bucket. Then it releases the said arms B5, andB7, and the spring U3 (Fig. 7) lifts up arm u1 and brush U5, while armu2 and the other brush U5 drop of theirown Weight. s

There is also a brush Y2 for the outside bottom of the bottle, and thisis shown in Fig. 5a in its retracted. position and in Fig. 7 in itsadvanced position. AIt is mounted on and forms the front face of theaforesaid pusher O'I on the rod O0. By this means the effect of frictionagainst the rotating bottle by reason of the impact of the pusher on therotating bottle is averted, and the cleaning of the bottom of the bottleby its rotation against the brush Y2 which intervenes between the bottleand the pusher O", is ensured.

When the bottles are pushed out of the buckets of the main carrier bypusher O7, they come out horizontally between the body brush R" belowand the exible belt R5 above. In consequence they then have no rigidcentering. Yet a definite centering is required, if an inside brush isto be entered through the mouth and lneck of the bottle to scrub itinternally. I therefore provide for such bottle a beveled mouth pieceS1l1 (see Fig. 7, Sheet 7, and Fig. 5a and Fig. 6), which may be movedup against the mouth of the bottle, as

shown in Fig. 3. when the bottle is moved back into the conveyer. Thelevel of this mouth piece S1'1 will centralize the bottle on itsemergence from the conveyer and while itis still being rotated by theflexible belt R5. While the bottle is thus centralized, I project intoit, through its mouth, an internal brush K4 (Fig. 7) mounted on a rod K5which is thrust out through the center of the aforesaid mouth piece S14.The bottle is rotating in one direction while the internal brush K4 isrotated in the opposite direction by the chain C40 as appears in Fig. 6.Therefore the brush K4 serves to scrub the inside of the bottles just asthe These arms, u1 and u2, are` That the conveyor and then horizontally,along the top length of the conveyor route back towards theirstartingpoint. The re-entry of the .bottles into the carrier buckets after thescrubbing is accomplishedby the reverse stroke of the pushing-out means.This will be described later when I take up the motive mechanism of theapparatus.

When replaced in the carrier-buckets after scrubbing the bottles travel,as just stated, upwardv therewith and then turn to a horizontal line oftravel for the purpose of rinsing and draining out.

mouth downward, come to a different form of track on which the bottlemouths bear. This track is open to permit lthe exit of the water,

For draining purposes `rthe lower ends Aof the bottles, which are nowtravelling and under it is a pan P20 (Fig. 7), to receive the Water.This pan P20 forms the bottom of the upper horizontal reach of the maincasing. This special track aforesaid is shown in plan at Fig. l0, Sheetl0, and in more detail in Fig. 8, Sheet 8, and in thev cross section atFig. 9, Sheet 9.

In these figures N1 and N5 represent a pair of parallel rails or rods,which I term guards, there being such a pair of guards for each of thefour lines of travelling bottles. Between each pair of guards N4 and N5and at a lower level runs a narrow rail N0 standing on edge. As appearsin thecross section, in Fig. 11, the bottle mouth rests on thisknife-edge rail N0 with. the guards N1 and N5 on either side of thebottle head. The wheels B17 of the carrier chain run on the outside.tracks N9 and N10 formed by flanges on the inside of the casing.Justfbefore the bottles reach this special drainage track they ride onthe normal form. of rail shown at N" and N0 in Fig. 10.

. and from said rails N"I and N8 the bottles slide off onto the rail N5as just mentioned. The guards N1 and N5 are formed in sections, and, asclearly .appears at the left of Fig. 8. springs QQ are interare carriedby a shaft X100. Shaft X is mounted upon and between adjustable slidesX11 which are supported between the spaced arms X12 of `a frame bracketX13. Slide X11 is provided with an ear X11 and the frame bracket X13 isprovided with a corresponding ear X15. Extending between and throughthese ears is an adjusting boltvX10 which, when tightened, draws -theslide X11 upwardly to thrust'the shaft X100 and the sector N'Iradiallyoutwardly of the entire apparatus whereby to tighten theconveyor chain A1".

In the length of the aforesaid rail N0, there are included at intervalsthe spray nozzles F20, as appear in Figs, 7 and 10. The water comes tothese nozzles,`F20, by cross pipes L10 (see Fig. 10, also Figs. 10E1 and1015,` Sheet 10), which branch from the main water pipe L15. At eachpaint where a cross pipe L10 branches from the main L15 there is acut-off valve L20, the details .of which are shown in Figs. 1011 and105. In Fig.

100 that valve is open and from the main L15 Water can flow freelythrough a hole in disc L20 to cross pipe L10 and the nozzles F20 thereolBut the said disc L30 is fixed to the pipe L10 and by a slight rotationof said pipe L10 the disc L20 may be also rotated to cut off the flowfrom main L15 as shown in Fig. 100. The required cutoff rotation of thepipes L10 is afforded by the reciprocating rod E10 which works a linkE20 that is connected to a short lever arm E15 on each of the crosspipes L10. 'I'hus by means of the rod E10 all of the spray nozzles maybe turned on or turned off simultaneously. The sprays from nozzle F20are of fresh water to remove the caustic water remaining on the bottlesafter their soaking in the bottom tank which I have heretoforedescribed. Referring to the showing of the aforesaid spray nozzles F20in Figs. 7 and 10, there is shown mounted on the cross pipe L10,adjacent to each nozzle, a lug G10. As each bottle comes into a verticalline with a nozzle F20, this lug G10 is raised, by means just described,for rotating pipe L10, to turn on the spray. The lug hits the head ofthe bottle from behind, and thus makes the bottle stand up straight forreceiving the spray through its mouth, whereas the bottle wouldotherwise stand in a slightly inclined position, as heretofore stated.Thus in Fig. 'l each bottle that is directly over a nozzle F20 isstanding up vertically, the setting-up lug G10 being up against thebottle mouth. On the contrary, the other bottles are in their normalinclined position, due to the fact that the carrier buckets are largerin diameter than the bottles to allow of the free movement of thebottles into and out of the buckets, and avoiding a tight t such aswould involve extreme accuracy in the spacing of the brackets withrespect to the bottles. Such accuracy would be impractical. Moreover thelarge sized buckets will permit of bottles of differing sizes up to thelimit where the bottle would t too tightly.

Besides the internal rinsing of the bottles by the spray nozzles F20,which I have just described, they are also rinsed externally by spraysdirected on them from above. This is shown in Fig. '7, at the top of thefigure, where two sprays R10, R10 are also applied to the outside of thebottles. It is also shown in the sectional view of Fig. 9.

After being rinsed, as I have just described, the bottles on the carrierare transported by the main conveyor to the end of the machine, wherethe track bends over the three-armed angular support X (Fig. 5), andstarts downward. Just below the hood X containing the aforesaidthree-armed, angular support X5, there is shown, in the same figure,(Fig. 5), a pusher rod OJ which acts like the above-described rod O8 topush the bottles out of the carrier buckets. As the bottle emergesfinally from its bucket, it slides onto a short, slightly inclined;chute W10 (see Figs. 2a and 2b, Sheet 2, also the plan view in Fig. 4)which is normally stationary.

The lower ends of the chutes W10 are supported upon a shaft Z10 which issupported at its ends in the respective side members of the frame of theapparatus and the shaft Z10 therefore forms the pivot about which thechutes W10 may oscillate.

From chute W10 the bottle slides onto a second chute W20 which tilts upat itsfront end, as shown in Fig. 2b, and deliversthe bottle into astanding position on topof an auxiliary transversely moving chain-tableQ10. The bottles are stopped from falling off the chain-table Q10 by,l

a vertical board V10 which (as shown in Fig. 1 and Figs. 2 and 2b and,in. plan, in Fig. 4) extends across the line of travel of the tilted-upmoves, in that Fig. 4, from left to right.

also pinned to shaft I'I.

bottles and parallel to the edge of the table Q10. This board V10 issecured to pivoted arms V120 and restrained by a spring V11 (see Fig.1). The bottles have now arrived at the chain-table Q10 (see Fig. 4)which moves from left to right (looking at the machine from its entryend, which is at the right of Fig. 4), and carries the bottles to theauxiliary longitudinally-moving chaintable Q2, shown at the top of Fig.4, and there 'Ihis chain-table Q2 brings the bottles to the deliverytable X20 which. stands at the right of the entryconveyors in Fig. 4.Thus the bottles, which were rst applied to the entry conveyors, arefinally delivered on the table X20 at the same end of the machine atwhich they entered. In the meanwhile they have encountered the soakingoperation in the bottom tank, have been scrubbed, rinsed and drained,and finally are brought to the delivery table X20, located right besidethe entry-conveyor, where they rst entered the machine.

I will now describe the motive apparatus, which has kept the bottlesmoving along the above described course, and, finally, the safetyprovisions for stopping the machine in the event of a mishap to one ofthe bottles in its progress through the several operations.

The prime mover is a motor, preferably an electric motor, M (shown atthe upper right in By a belt M2 the power of motor M is transmitted to adriving pulley M1 on the main shaft 2. This power plant is located inthe open space between the horizontal soaking tank below it and thehorizontal casing above it in which the l bottles are rinsed and drainedafter their scrubbing on the vertical run of the main conveyor. Mainshaft 2 drives the sprocket chains M3 and M1 (Fig. 12).

The chain M3 drives the shaft I of a pump S100 (also shown in Fig. 3 atthe extreme right), while the chain M4 drives shaft 3 which is thebrush-n operating shaft (see also Fig. 3). The Worm on shaft 5 is drivenfrom the aforesaid main shaft 2 through the gearing 50 (as shown in Fig.5) and drives a transverse shaft 6 from which the chief movements of themachine are derived. Thus (referring to Fig. 5) on the said shaft 6 is alarge wheel 'I that contains a. cam track 8 in which track runs a roller811. This cam B gives a reciprocating movement to the parts ahead of it,whereas, the movements of the parts behind it have, up to this point,been rotary. The aforesaid roller 3 is mounted on a link III which, atits left end, reciprocates a lever-arm II and at its right endreciprocates a lever-arm I2. That reciprocates push-off pusher O9.

Thesaid lever-arm II gives several required reciprocating movements. Bymeans of the link I3, it reciprocates five upright lever-arms whichcenter on the cross shaft I`I at the bottom of the machine in Fig. 5.For a more complete showing of these five lever arms, it becomesnecessary to turn to Fig. 9, where, of said five lever-arms, the twoouter ones, I5, I5, are pinned to shaft I1 and move therewith, as doesalso the center arm I 6 But the intermediate arms I4 are loose on rtheshaft IL The two outer arms I5`are respectively jointed at their outerends to the rods O4 which extend to the rear end of the machine (asappears in Fig. 3) Where they are joined to the cross bar T20 (see Fig.6) which carries Vthe four pusher rods Oa that serve to eject bottlesinto the scrubber from the carrier buckets to permit the scrubbingoperation. The

stroke of the aforesaid rods O'1 and O8 together with the cross bar T20is determined by the oscil-` lating stroke of the aforesaid shaft il towhich the lever arms I5 are likewise pinned. The contact lever arm I6,also pinned to shaft I'I, is the intermediate lever-arms I4, which arenot pinned to shaft I'I, are operated in one direction, i. e., to theright in Fig. 5, by a strong spring Q30 anchored at Vits right end tothe link I3 which is jointed to the aforesaid cam-operated arm I.

So when the arm II, by its link i3, pulls positively on control leverarm I6, pinned to shaft 'I to operate that shaft, it also 'exerts ayielding pull through spring Q30 on the intermediate leverarms Irl whichare not pinned to shaft I 1. The arm It is provided with a boss I6' asshown in Fig. 5` and it is to this boss I6 that the link I3 is attached.When thus spring-pulled, a stop Ill which forms a cross connectionbetween the arms I4 abuts against the said control lever-arm I5. Attheir upper ends the aforesaid lever arms It (see the right-hand end ofFig. 6) are conmoved by the aforesaid lever arms I4 to the left (seeFig. 3) against the force of spring W50 and is itself connected to themouth piece S14. When a bottle is pushed out of the carrier forscrubbing by the aforesaid pusher O0, it engages the mouthpiece S1*1 andmoves lit back against the said spring W50. Conversely the mouth-pieceS14,

when worked by lever arms I4 acts to push the bottle back intothecarrier after the scrubbing.

The movement of the lever arms I6 is positive in, accord with` theoperation of the link I3, whereas the movement of the lever arms I4 lagssomewhat during the tensioning Aof the spring Q20.

y Therefore the bottles as they leave the cells of the conveyor areguided by the mouthpieces S11 before the mouthpieces are actually movedby the lever arms I4. In the event of aofailure of the bottle torreenter the carrier cell or bucket D12 the spring W50 will yield andultimately the aforesaid sleeve V25 will hit a push button W20 and causethe machine to stop. 'I'he stopping can also be caused by pressingmanually on v the button W22.

lAlso from the aforesaid lever-,arm II extends (see Fig. 3) leftwardlyand upwardly a rod 26 that 'goes to and operates the-above-describedbottle-straighteners G10.

We may turn next to the work performed by the lever-arm I2, which, likesaid lever-arm II, is reciprocated by the large cam 8. As appears inFig. 5, lthis lever-arm I2 is jointed at its lower end to the left endof the aforesaid push rod O which performs at the front end of themachine the same function that is performed by rod O at the rear end.That is, it pushes the bottles out of the vertical line of buckets orcarrier cells of the main conveyer at the front of the machine. `At thisfront end it pushes them out onto the aforesaid chute W10, preparatoryto their progress to chute W by which they'are tilted into uprightposition. Leverv I2 and pusher rod O0 appear in Fig. 2, as well as inFig. 5. 0n the same center 40 with lever arm I I is one of the sprocketwheels driving the main conveyer belt, and, as appears in Fig. 3, theshaft 40, which carries the said sprocket wheels 50 is drivenintermittently vby a stop-gear |00 driven by a gear 20|) on theaforesaid shaft I5. This explains the intermittent travel of the mainconveyer.

The chutes W20 that tilt to upright position the outcoming bottles, areworked by a rock-shaft J2,'in Fig. 1, which also. works thebottle-follower J1 aforesaid. This shaft J2 (as best appears at theright of Fig. 85 and in the upper left of Sheet 4) is oscillated by ashort lever J10 and the cam J15 on the shaft 4. Shaft 4 is driven bybevelled gears from the main shaft 6 (see also Fig. 4), and, by a chainJ15 driven by sprocket Wheel lJ11, drives the shaft I8, which, in turn,operates the conveyer Q2 through the gearing K10, K1; The oscillatedshaft J2 is connected (as shown in Fig. 4), by a rod 29 to the shaft J2of the tilting chute W20. The Worm on shaft I8 and the worm wheel onshaft comprise power connection between shaft I8 and the carrier E2.

The aforesaid guard-board V10 which is mount-l ed on the arms V120, hasadjustably connected to it the rod Z40 (Fig. 20) which operates thesafety stop Z50 through the link Z51 and shaft Z10. Thus if the bottlescrowd too numerously on the conveyer- Q10 they will push against theguard-board V10 and stop the machine. The arms V120 are attached to aslide-V121 upon rod Z40 and the slide V121 is adjustable on the rod Z40under the control of a bolt V122 extending through an apertured ear V123against which a wing-nut V50 advjacent end 45 of the link Z40 upon thebolt V122 is caused to, bear by reason of'a spring V11 extending betweenthe slide V121 and a point of attach-y ment upon rod Z10 as shownclearly in Fig. 21-
